I dont think our NSX's have Android Auto??? All I know is every time my phone connects when I start the car it says something like "phone not compatible with apple car play"
Do you have the android auto app downloaded? If not you will need to do that and set it up before android auto is available. I can't remember the last time I even messed around with Bluetooth in my own cars. Apple Carplay and Android auto are phenomenal IMO. I've used exclusively apple carplay for nearly 2 years now and use it every time I am in the NSX or any Acura for that matter.
